Buriti core carbon (CCB) was produced from the reject of artisanal production of its fruit for the extraction of oil, heated to 400ºC. Then, the CCB was activated at temperatures of 800ºC and 900ºC. Adsorption tests were performed to evaluate the discharge of these activation temperatures in the adsorption of a solution of copper (II) to a known initial concentration of 50 mg/L. After having examined the results, it was decided by the activation of coal to 900ºC. The activated carbon of the buriti core (CACB) to 900ºC was characterized according to commercial properties such as specific area, porosimetry, apparent and real densities, porosity of a bed fix, scanning electron microscopy, ash content, pH, moisture, fixed carbon and acid surface functional groups present in the CACB. The results showed a higher removal efficiency of copper (II) to the diameter D < 0.595 mm, for the contact time of 300 minutes, for the pH of 4.01 and the initial concentrations of copper (II) 50 and 80 mg/L. Mathematical models of Langmuir and Freundlich were applied to the data of adsorption equilibrium. The mathematical model of Langmuir was the best fit to the data of balance. The Langmuir’s mathematical model was the best fit to the data of balance. According to data from the kinetic equilibrium, it was observed that from the contact time of 15 minutes all the equilibrium concentrations were below the allowed maximum of 1,0 mg/L under the law CONAMA nº 357/2005 for release effluent into aqueous environments. The experimental results obtained are indicative that it is possible to remove copper (II) from industrial effluent using CACB activated physically at 900ºC for a period of 60 minutes.
